[kettledrum]

I'm not too sure about the ranks of members of Sir John Falstaff's troops - although Pistol is referred to as Ancient Pistol which might be equivalent to corporal.

Another possible candidate is Bardolph.

[Octavius]

PISTOL : Not I I tell thee what, Corporal Bardolph, I could
tear her: I'll be revenged of her.
